Hi ! I have install Naza M V2 with GPS and DJI lightbridge on a walkera QRX350.
I use a Graupner MC-20 transmitter and the receiver is a Graupner GR16.

The problem is that when i unlock motors, motors start run in low speed even the throttle
is at 0%. Moreover, when increase the throttle the power of motors is not enough to take off
the drone. Tried to calibrate ESC through receiver/transmitter but looks that calibration was
unsuccesful. In fact ESC didn't enter calibration mode even i did the steps as mentioned in the manual.

Any idea/help pls ?

This is normal. The motors are meant to spin when Naza is armed. Increase the throttle to above 60% and it will automatically take off

hi ! even if i increase the throttle to 100% the quadro don't take off.
is obvious that the power of motors isn't enough for take off even the throttle is at 100%.
however, are you sure that is normal to run the motors after unlock even the throttle is at 0% ?

You could change Motor Idle Speed in Naza Assistant
Please check T channal in assistant is 100% when you push the RC throttle to top
Moreover, you could modify the RC throttle endpoint in Graupner MC-20 transmitter if it has that function

I got this after calibratiing my ESC's


Can somebody please help me here?
Unless this whole copter ends up in flames ia a real flamewheel 450!!!
